Sequence features of the black grouse MHC-B region. A. Position of the sequenced fosmid clones. Dotted lines indicate the heterozygous parts. B. Gene annotation of the MHC-B of black grouse. Different shadows indicate different MHC gene families defined from human MHC. From dark to light: Class I, Class II, Class III, others. C. Average 454 sequencing coverage per nucleotide for each expressed region. D. Positions of repetitive elements and tRNAs. E. CpG islands in 100 bp window size. F. GC contents in 200 bp window size.
